Plan is to have a flat screen on a wooden inclined part. motherboard below with i5 / Win7or8 and good video card + speakers toward the ground.Budget should be 500/600 $ .... cant wait to start this as a winter project

They will include screen rotation at some point, they showed off a virtual pinball machine running pinball arcade last week(check their facebook page for the video), but it will be after new year before they implement it.
